SISTEMAS DE COBERTURA MÓVILES PARA PRODUCCIÓN HORTÍCOLA Y FLORÍCOLA PARA LA AGRICULTURA FAMILIAR

La agricultura protegida permite minimizar las restricciones que el medio ambiente impone al desarrollo de las plantas, obteniendo cultivos agrícolas fuera de su ciclo natural y en menor tiempo, capaces de enfrentar con éxito plagas y enfermedades, con mejores rendimientos en un espacio reducido, sanos y con un mejor precio en los mercados. La presente tesis tiene por objeto de estudio la agricultura protegida para los pequeños productores familiares. El propósito de la investigación es brindar una solución accesible teniendo en cuenta sus limitaciones económicas. Bajo este marco surge la idea de desarrollar un set de vínculos, que combinados con materiales estándar permiten armar un macrotúnel que responda a las necesidades de la agricultura familiar

PIANO DI GESTIONE DEL SITO UNESCO LE CITTÀ TARDO BAROCCHE DEL VAL DI NOTO

An effective asset management system must consider three essential elements, namely a reference legal framework that defines the reasons for its very existence, an institution that shapes organizational and decision-making needs and resources, human, financial and intellectual, used to make it operational. Having clarified the areas and the meaning of these three decisive elements, it becomes easier to plan, implement and monitor the actions identified to ensure the conservation and management of the assets and values associated with them in a sustainable way. The management systems are aimed at achieving results that benefit the site and its stakeholders and include planning, implementation and monitoring cycles, aimed at carrying out activities aimed at conservation, interpretation and access to the site, also taking care of the sustainable use and sharing of benefits. Obviously each management system must be regularly reviewed and updated in order to respond to changes in the site and in the context, making the necessary adjustments. With the powerful work undertaken by Civita to update the three Management Plans of the UNESCO sites of "val di Noto", "Siracusa and the Necropolis of Pantalica" and "villa romana del Casale" of Piazza Armerina, the goal was to develop an integrated system of the three different floors, related to three different contiguous sites, which has no precedent. From this unprecedented and extraordinary coordination it will be possible to reap mutual benefits, economies of scale and common strategies, for example, linked to the unpredictability of the risk of natural disasters or fluctuations in financial resources. Particular emphasis must be given to the participatory approach used in the drafting of the three Management Plans, through the shared understanding of the site, and its identity, by all interested parties with their involvement in the construction of technical contributions that is premised on involvement in management processes and also foundations- efficiency in terms of reactivity that only the continuous exchange of results and outputs can ensure, feeding the monitoring and reprogramming phases

Evaluation of insulin resistance in a cohort of HIV-infected youth

AbstractObjectiveMetabolic abnormalities, including impairment of glucose homeostasis, have been well characterized in HIV-infected patients. In contrast to adults, insulin resistance and diabetes mellitus appear to be relatively uncommon finding in youth.DesignWe assessed insulin resistance, and associated risk factors, in a population of vertically HIV-infected children and young adults, when compared with a control population of healthy children.MethodsAt the time of enrolment, weeks of pregnancy, birth weight, sex, age, weight, height, body mass index (BMI), pubertal stages, CDC classification, blood pressure, clinical lipodystrophy, hepatitis B or C co-infection, antiretroviral therapy, CD4 T lymphocyte counts, and HIV-RNA levels were recorded. Fasting plasma glucose and insulin levels and homeostatic model assessment-insulin resistance (HOMA-IR) were determined. These parameters were compared between HIV patients and healthy controls with multivariate analyses.ResultsFasting insulin levels (OR=1.21,P<0.001) and glycemia (OR=0.89,P<0.001) were significantly different between HIV-infected patients and controls. Antiretroviral therapy duration (r=0.281,P<0.05), triglyceride levels (r=0.286,P<0.05), age (r=0.299,P<0.05), and BMI SDS (r=0.485,P<0.001) were significant predictor variables of insulin resistance, expressed as HOMA-IR. Moreover, clinical lipodystrophy seems to be strongly correlated to glycemia (P<0.05), triglyceride levels (P<0.05), serum insulin levels (P<0.001), HOMA-IR (P<0.05), and also with therapy duration (P<0.05).ConclusionsBoth HIV infection and antiretroviral therapy demonstrate differential effects on glucose metabolism in HIV-infected children. Targeted prevention of insulin resistance and diabetes mellitus in HIV-infected children and young adults is needed in order to avoid the associated long-term complications that would otherwise occur, given the improvement in life expectancy of HIV-infected individuals
